id3v2.4 allows multiple artists and multiple genres and afaik they are seperated by NULL

for artists this works but for genres it doesnt. im sorry to waste your time, but how are the genres separated then? because if i change the sources of eyed3 to allow NULL character in genres my music players all recognize the different genres.

edit: besides that, i was using an old version and didnt notice. works in 0.7.5 despite being not valid...
